UNITED STATES LOUIS BARTHELEMIY CASTETS, OF BENEJACQ, FRANCE.

EVAPOBATING- APPARATUS.

Application filed October 23, 1922.

T 0 all whom. it may concern:

Be it known that I, LOUIS BARTHELEMY CAs'rnTs, citizen of the Republic of France, and resident of Benejacq, Basses-Pyrenees, in the said Republic, manufacturer, have invented certain new and useful Improvements in Evaporating Apparatus; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The apparatus forming the object of my invention is designed to distill, evaporate or concentrate all and any bodies or substancesof a nature to undergo such operations and is based on the phenomenon of emulsive propulsion, a phenomenon brought about by the running of the material under treatment in a. direction contrary to that of steam (coun tor-flow) My apparatus can work under normal or under reduced pressure, according to the requirements of the bodies to be treated.

In order to make my invention more clear-- ly understood I have illustrated, as an example, an embodiment thereof, namely, an apparatus designed to work under normal pressure, in and by the appended drawing, wherein: Figure 1 is a vertical section of my apparatus and Figure 2 is a plane view of the same with certain parts broken off.

My apparatus comprises: a b X having an upper compartment (4 to receive the material to be treated, such box being fitted with a perforated plate b above the bottom 0 of the upper compartment a and resting on a second compartment 03. On the sloping bottom of the latter which conserves the heat is set a flat rectilinear coil 6 to e the coils of which are surrounded with or encased in a steam circulation double envelopeor casing f.

An upward tube 0, running from section e of the coil, leads to a chamber a which has a heating plate 9 provided with a steam circulation box h and carries a swan neck 2' opening into a condenser of any sort or type, whether a surface condenser or a 1111X ture condenser. The condensated products are led into suitable containers, not shown,

In the drawing, direction of the stream flow is indicated by a full line arrow and SeriaI No. 596,468.

direction of the run of material by a dotted line arrow.

The working is as follows:

Steam is fed into steam box it through nozzle j and, after having gone through the whole length thereof, passes into double casing Z of tube is through tube m, circulating therefrom through jacket or casing f of coil sections 6 to e and getting out through a blow-01f located on section 6 fitted with a nozzle 0. The material to be treated is introduced into box a and, through the holes in perforated plate 6 which retains whatever impurities the material may contain, accumulates in the space between said plate Z) and bottom 0.

Through tube 7? connecting nozzle 9 with coil section 6' and provided with a control cock 9, the material is introduced into the coil, through all the members of which it runs, to go up through tube 70 and discharge on to heated plate 9. From there the vapours escaped are led by swan neck 2' to the condenser and the liquid material flows out through outlet nozzle 8.

Of course the number of coil turns or sections is not limited and my apparatus ca be built with several superimposed coils.

The purpose of tubes 27, u, o, is to permit, in certain cases, agents adapted to foster separation of the various components of the material under treatment to be introduced into the coil.

Having now particularly described and ascertained the nature of my said invention as well as the manner in which the same is to be performed, I declare that what I claim 1s:

1. In an evaporator, the combination with a box having an upper and a lower heat conserving compartment: of an inclined, jacketed serpentine in the lower compartment, the interior of said serpentine connected to the upper compartment, means to admit steam to the jacket near the discharge end of said ser entine and an evaporatin plate onto whic said serpentine discharge from its upper end.

2. In an evaporator, the combination with a box having an upper compartment and a lower heat conserving compartment and a screen in said upper compartment above the bottom thereof; of an inclined, acke-ted serpentine whose lower receiving end enters the bottom of said upper compartment below said screen, a hot plate, a steam box below the same, and means to connect said steam box and the upper end of said jacket, the upper end of said serpentine discharging onto said plate.

3. In an evaporator, the combination With a box having an upper open compartment and an inclined screen above the bottom of said upper compartment; of a heat conserving lower compartment and a jacketed, inclined serpentine in the lower compartment connected at its lower receiving end to said upper compartment below said screen, a chamber having a hot plate forming its bottom, a steam box covered by said plate and means to connect said box with the jacket at its upper end, whereby said serpentine is heated by a counter current of steam and the upper compartment is heated from the lower compartment.

In testimony that I claim the foregoing as 20 my invention, I have signed my name.

LOUIS BARTHELEMY CASTETS.
